Teeth bleaching is a procedure for changing the color of your teeth. Each tooth includes a variety of organic molecules (including antibiotics from the tetracycline group), which with its distinctive color lead to the overall yellow/yellow-brown shade of the tooth. With tooth whitening is designed to make your smile more attractive and radiant, giving your teeth a more bright, brilliant hue.

Whitening of discolored mortified teeth is achieved by placing bleaching gel on the tooth. After several days the procedure can be repeated till achieving the desired result.

Our answers to the frequently asked questions

Detailed information on tooth whitening with the KöR Whitening System

Why does the KöR whitening system work so well?

It restores the ability of your teeth to absorb oxygen. The bleach gel contains oxygen, which penetrates deeply into the tooth, destroying color molecules.

Is it safe?

Yes! The product is clinically tested. It is applied to millions of patients without damaging their teeth and gums.

Does it matter how old I am?

The ideal age for teeth whitening is 14 years. The younger the teeth, the better they bleach. The KöR, however, can bloom your teeth very well even when you are 90 years old.

Will my teeth look unnaturally white?

No. True teeth can not look unnatural. If you’ve ever seen unusually white teeth, then it’s probably been a veneer or a crown.

Can smoking, coffee, tea and red wine reduce the effect of bleaching?

Food and drink will not affect your white teeth, with easy home care.

How does the bleaching system work?

You will choose with our dentist which KöR system is right for you. You will wear the brace at home while you sleep for 2 weeks. Depending on the desired result, you can make 1-2 bleaches in the dental office.

How long does the bleaching effect last?

Unlike other bleaching systems, with easy maintenance at home, the effect of bleaching will be constant.

Is there pain or discomfort?

After many years of clinical trials and tests, the KöR developed a system that in most cases did not cause sensitivity. If so, it is minimal.

How white will my teeth become?

KöR bleaches teeth dramatically, often up to 16 shades. Even the tetracycline colored teeth can be significantly bleached.

Will my crowns and veneers also whiten?

No. If you have them in the frontal area, you will probably have to change them after bleaching.

Cause you discomfort whitening strips?

No. They are thin and comfortable, you will even forget that they are in your mouth. There is no danger that the whitening gel will leak out of them at night.
